And something else. This 'small industrie' is also a seller's market. With the increase in the popularity of the music type there will be more demand. One thing about any and all the builders in LA, they all build to quality, i.e., their reputation and intergrity are represented by their creation, irregardless of the type of corner joint they use. It is a credit to them that they do not 'cut corners' and mass produce a bunch of junk.

Don't forget about Jude's Bon Temps in Texas. I know you included him generically with LA boxes.

Just because Port Arthur, Groves, Orange, Beaumont, and even Winnie are on the West side of the Sabine River, that only means that they are geographically in Texas. Culturally, they are part of Louisiana. The fish in Sabine Lake swim to both sides and never know the difference.
